Static Timing Analysis - Prime Time

How many minimum modes i should qualify STA for a chip
1. Scan Shift mode
2. Scan Capture mode
3. MBIST mode
4. Functional modes for Each Interface
5. Boundary scan mode
6. scan-compression mode

How many minimum process lots , should STA be qualified.

1. Fast corner
2. Slow corner
3. Typical corner
How many minimum Timing , Should STA be qualified.

1. normal delay mode(with out applying deration)
2. On-chip variation mode (deration applied)
3. SI mode (Signal integrity cross talk impact on STA)
How many minimum STA runs should we needed to address = 6*3*3.
